6 When added, the water should be neutral or slightly acidic. Alkaline ingredients are added after thorough dispersion of the cellulose ether. After the grinding process, the latex can be added in let down stage. HECELLOSE should never be added as a dry powder after latex addition because the latex will coat the particles of HECELLOSE and dissolution time will be greatly a dry powderAs a slurryAs a stock solutionStock solutions are made by adding HECELLOSE powder to water and stirring until the thickener is using a HECELLOSE , the water should be neutral or slightly acidic. If it is alkaline when adding HECELLOSE , the thickener will dissolve too quickly, forming an insoluble gel instead of a solution and generate micro foam. If you re planning to store stock solutions for a prolonged length of time, we recommend that stock solutions should be protected from microorganisms by using a suitable are readily made by dispersing a HECELLOSE either in water or in a suitable organic solvent.
